Outbreak Of Brucellosis Research Articles

Brucellosis outbreak attributed to ingestion of umpasteurized goat cheese

In six cases of Brucella melitensis infections the common etiologic factor was the ingestion of raw goat cheese. Presenting complaints were variable, but a constant feature was persistent fevers that frequently were present for months. Evidence of liver cell dysfunction was present in each case, and in two, biopsy disclosed diffuse hepatitis with focal necrosis. The diagnoses were initially based on high titers of Brucella agglutinins and later confirmed by positive blood cultures. A good clinical response was induced by antibiotic therapy ( tetracycline plus streptomycin sulfate), but in two cases a Jarish-Herxheimer reaction occurred during the first 24 hours of treatment.

Application of Research to Bovine Brucellosis Control and Eradication Programs

Recent research on brucellosis has resulted in new developments in the broad areas of immunity, diagnosis, and Brucella characterization. Application of these developments is necessary to continue the progress of the control program toward the goal of eventual eradication of bovine brucellosis.Heifer calves vaccinated at three, four, or six months of age with Strain 19 developed an immunity against brucellosis equal to that in heifers vaccinated at eight months or older. Calves vaccinated at two months also developed a serviceable immunity. Application of vaccination at younger ages will practically eliminate persistent vaccinal titers that have caused some inaccuracies in interpretation of standard diagnostic tests.Specificity of several diagnostic tests has been increased considerably, thus increasing our ability to identify the infected animals. Most of these have been used to supplement the seroagglutination tests in problem herds. The card test is being evaluated further by applying it routinely in states that have not attained a modified certified status.Addition of Brucella phage and oxidative metabolic tests to the biochemic and serologic tests will enhance our capabilities of characterizing Brucella responsible for new outbreaks of brucellosis and our ability to contain such outbreaks.

Localized outbreak of brucellosis in Liberia.

Summary This is a report of an outbreak in Liberia of brucellosis, a previously undiagnosed disease in this country. The outbreak had its origin in Guinea and its transport to Liberia was traced. Details are given in regard to signs, symptoms and laboratory findings, and conclusions are drawn in regard to diagnosis and virulence of the disease process. Cultural identification of the organism and species differentiation were not possible owing to lack of special media in an area where the disease had not previously been noted.
